Abstract
PURPOSE:To reduce costs and variances in accuracy by supporting a revolving shaft by a pair of ball bearings, and integrally providing a magnetic field DC motor including a position detecting mechanism abd a speed detecting mechanism between these supports. CONSTITUTION:A motor revolving shaft 2 is supported freely rotatively by a pair of ball bearings 11, 12, and a rotary polyhedral mirror body 1 is installed on the outer side of these bearing supports. Further, a rotary magnet 8 is provided between the bearing supports of the revolving shaft 2. The outside diameters are made smaller in order of the ball bearing 11 which is nearer to the rotary polyhedral mirror body 1 out of a pair of the ball bearings 11, 12, a rotor magnet 8 and the other ball bearing 12. In this way, the light deflector which is equivalent in accuracy to those which are meticulously worked to high accuracy as in the prior art, is nevertheless small in the variance of accuracy, and is stalbe in quality may be made at a small size and a low cost, with the simple constitution.
